Pleurotus eryngii mycelium growth temperature range is 22-27 °C, the optimum temperature is about 25 °C, higher than 30 °C when the hyphae grow poorly. Pleurotus eryngii is a constant-temperature robust mushroom, the temperature difference is too large, unfavorable to the occurrence of the primordium, the temperature of the mushroom is 10-18°C, the optimum temperature is 12-16°C, and less than 8°C will not present the primordium, higher than 20 °C prone to malformation mushrooms, but also disease, causing dead mushrooms, rotten mushrooms. The fruiting body has a growth temperature of 10-21°C and an optimum temperature of 10-18°C. The mastery of temperature varies from strain to strain, and special attention must be paid to the characteristics of the strain when introducing it.
2, how to manage the bags of Pleurotus eryngii?
After the bacterial bag is full, it is maintained for about 7 days. When the hyphae are fully physiologically matured, they are transferred into the mushroom shed. Cut off the yam or remove the tampon. After removing the collar, turn the bag over or cut it off to expose the material surface. The humidity in the shelter is controlled to about 95%, the light intensity is 1000 lux, and there is a small amount of ventilation. After about 15 days, the surface of the bag mouth is formed with a white spot-like primordium. In autumn, measures should be taken to properly reduce the temperature of the greenhouse. In the spring, measures should be taken to increase the temperature of the greenhouse, increase ventilation, maintain the humidity in the greenhouse, increase the number of primordia, and then differentiate the original primordium and emerge young buds. The temperature of the greenhouse in this stage should be strictly controlled below 20°C. Otherwise, it cannot be budded.
3, how to manage the bag of Pleurotus eryngii after mushrooming?
The mushroom surface is cleaned up and the mushroom shed is cleaned. After the spring planting, the fungicides such as chrysanthemum insecticides and carbendazim are sprayed all together, and the shade is sealed so that the bacteria bags can recuperate. When the autumn plants are sprayed, only the fungicides can be sprayed. . After the original surface is reproduced, the mushroom management can be performed again. Generally can receive 1-3 tide mushroom, biological efficiency 50% -60%, commodity rate 80% -90%.
4, how to deal with Pleurotus eryngii fruit body but the low commodity rate?
If no spawning is done, after the layer is differentiated, a small number of buds will grow on both sides of the bag. Due to the limitations of nutrition and space, most of these mushroom buds cannot grow into commodity mushrooms. Therefore, budding must be conducted in time. The principle of sparse buds: When the buds are formed, they have 4-6 pieces of mushroom buds with good position, mushroom shape, and similar size on each side. When the fruiting body grows to 2 cm or so, another optimization is performed, leaving 2 on each side. -4. In this way, higher product rates can be guaranteed.
